BackgroundIn prepectoral direct-to-implant breast reconstruction using the acellular dermal matrix (ADM)-assisted technique, breast volume asymmetry can occur. We hypothesized that ADM size influences implant size selection in prepectoral breast reconstruction with implant coverage using an ADM. We investigated factors influencing implant size selection and provide guidelines for surgeons.MethodsA retrospective chart review was performed to identify all patients who underwent prepectoral direct-to-implant breast reconstruction between January 2017 and October 2020. We assessed patient characteristics, preoperative expected implant volume, ADM size, volume of implant used in surgery, and symmetry scale of aesthetic item scale (AIS) 6 months after surgery. We compared the symmetry score of AIS between a group in which the preoperative expected silicone implant size (ES) was used and a group in which a silicone implant of a smaller size than planned (SS) was used.ResultsPatient characteristics, including age, body mass index (BMI), and excised breast volume, were similar between the groups (P > .05). ADM size had a significant effect on implant size selection (odds ratio = 1.760, P < .01). The symmetry score of AIS was higher in the SS group.ConclusionsADM size must be considered when selecting implant size in prepectoral direct-to-implant breast reconstruction using the ADM-assisted technique.Copyright © 2022 the Author(s).
